Research And Implementation Of P2p-based Campus Network Streaming Video Live

In the twenty-first century, the Internet is an important media in the information society. Especially the Live Video, it wins more and more audience of all ages for its varied videos and vivid sound. Streaming media on-demand technology and multicast technology is more popular Internet applications of technology to transmit video programs at present. Its extensive and real-time characteristics have become the primary source to access information and knowledge in worldwide. Although Streaming Media On-demand Technology and Multicast Technology has many advantages in Internet applications, there are some disadvantages, such as complex network deployment, heavy management, high cost, more bandwidth occupancy and so on.Nowadays Peer To Peer Streaming Model can be divided into two categories as follow. The first category is Tree Like Structure. It bases on Multicast tree protocol. It organizes nodes into a single tree or multiple trees for media distribution. ZigZag single sender and the SplitStream sender are more typical. The second category is non-structure. It uses goosip protocol and bases on data-driven to constitute a non-structure overlay network. Data are transmitted between nodes and nodes by using pull mode. PPLive protocol is analysed as an example.In this paper, the author focuses on the key technique of the NetLive System, basing on these two types of models in-depth analysis and comparison, proposes local priority ways in accessing the resources, improves the original DHT (Distributed Hash Table) program and explain the new algorithm design ideas and processes. The new algorithm reduces the bandwidth occupancy and greatly improves the quality and efficiency of streaming media transmission. The author successfully designs and develops a campus network based on P2P live video streaming system NetLive. The final part of this paper revealed the successful design of the NetLive systems by analyzing the test results in different environment. In the campus network environment, different types of qualification are given. The author widely tests and analysis the average query hops, local routing list, smooth degrees of program playing, the amount of information and provides the NetLive video broadcast systems a scientific and objective evaluation.
